1944-D Phillipine Ten Centavo

Nice coin from your Grandfather. It's a Denver mint. Total mintage of it was 31,592,000 pcs based on page 45, 2nd Ed. Aldo Basso' book.
My Sister also holds two of this 1944-D WWII era coin from our Father. You will notice its shield is different from the usual shield of the USPI coins, because this was made during the Commonwealth period in the Philippines.

Hi Fioti, all Philippine Commonwealth coins don't have denticles on its reverse but instead have a different design on its rim that may look as if they are bumps. One thing is not clear yet for me though, if the designer of Philippine coins during the Opening of the Manila mint during 1920 (Commonwealth era) is Ambrosio Morales, then it could be possible that this coin has two different designers of its obverse and reverse? Melicio Figueroa on the obverse and Ambrosio Morales on its reverse? I think I have to research for it...
